    Default Transmission difference b/w FJ 60, 62, HJ 61 and BJ 60's

    There is a lot of information available on net about the subject issue but no information on the following.

    I have a stock FJ 62, 3F which is with 4 speed manual transmission. The top speed is good with 3000RPM @ 120 KM/hr. The transmission is H41.

    I just want to ask the following questions,

    1. Can the transmissions of the subject vehicles be changed with each other WITHOUT any cut and weld or bell housing change with each other? Like for any reason, if i want to change the existing transmission, can i just fix the housing of the H42 or H55f with the existing engine?

    2. I know H55F is 5 Fwd but what is the difference between H41 and H42 as both are 4 Fwd?

    3. Also what do we mean by T-Case splines? They are 16 and 19 i think.

    Regards
